National Institutes for Quantum Science and Technology

Also known as NATIONAL INSTITUTES FOR QUANTUM AND RADIOLOGICAL SCIENCE AND TECHNOLOGY, National Institutes for Quantum and Radiological Science and Technology, QST

The National Institutes for Quantum Science and Technology (QST) is a Japanese national research organisation formed on 1 April 2016, when the Japan Atomic Energy Agency transferred some of its laboratories to the National Institute of Radiological Sciences, which was renamed the National Institutes for Quantum and Radiological Science and Technology; it has since shortened its name. Besides fusion it runs quantum technology, heavy-ion cancer therapy and synchrotron research. In fusion, QST operates JT-60SA at Naka, Ibaraki Prefecture, a superconducting tokamak built jointly with the European Union under the Broader Approach agreement to support ITER. JT-60SA produced its first plasma on 23 October 2023 and is, according to Wikipedia, the largest superconducting tokamak in operation. QST also takes part in the ITER project, and in August 2026 reported that an ITER toroidal field coil had passed an excitation test.
